What Should I Take on My First Marathon? The Ultimate Race-Day Kit List
Your first marathon is a logistics game as much as a fitness test. The right kit keeps you calm at the start and steady at mile 20. Use this checklist to pack exactly what you need—no more, no less—and see why the Swiftal adjustable running vest with Swiftal 500 ml collapsible bottles makes race day simpler.
Race-day essentials (pack the night before)
- Bib + safety pins (or bib magnets) — lay this on your vest/shirt.
- Timing chip (if separate) — attach to shoe.
- Running shoes + socks you’ve trained in (no new kit).
- Top + shorts/leggings suited to the forecast.
- Anti-chafe for underarms, chest, thighs, and vest contact points.
- Watch/GPS with course loaded or easy lap screen.
- Phone, ID, bank card (zip pocket).
Hydration strategy (simple and hands-free)
Most city marathons offer aid stations, but carrying your own makes pacing and fueling smoother. Two front bottles let you sip little-and-often without breaking rhythm.
- 2 × Swiftal 500 ml collapsible bottles — they compress as you drink (less slosh), fit neatly in the Swiftal vest, and are easy to refill quickly.
- Electrolytes (tabs or mix) for warm conditions or salty sweaters; drop a tab in one bottle, keep the other plain.
Rule of thumb: drink to thirst and conditions. Don’t overdrink; use aid stations to top up. See sources below for evidence-based guidance.
Fuel plan (gels/chews)
For most runners, aim roughly 30–60 g of carbohydrate per hour in a marathon; well-practiced athletes often target up to 90 g/h using multiple transportable carbs (e.g., glucose + fructose). Test in training to avoid GI issues.
- Gels/chews: pack 5–7, depending on your finish time and gel size (~20–30 g carbs each). Mark your watch with gel times (e.g., 30, 60, 90, 120 minutes).
- Carry method: front vest pockets for 2–3 gels, rear pocket for the rest; keep an emergency gel for mile 22.
Weather & comfort add-ons
- Throwaway layer for the start (old tee or space blanket).
- Light waterproof / arm warmers if rain/wind is forecast.
- Cap/sunglasses + SPF (apply before you leave; top up if sunny) — see NHS sun safety.
- Small tissues or wipes (back pocket).
How to pack your Swiftal vest (quick layout)
- Left front pocket: Bottle #1 (plain water). One gel behind it.
- Right front pocket: Bottle #2 (electrolytes on warm days). One gel behind it.
- Front zip pocket: Phone, card, ID.
- Rear pocket: Extra gels/chews, thin layer, tissues.
The Swiftal vest tightens at the chest and waist so bottles stay stable yet breathing is easy. Do a 20–30s jog-in-place test, then micro-adjust until bounce disappears.
Pacing & comfort tips
- Start slower than you feel. Adrenaline at the gun is real; hold goal pace or slightly under for 3–5 miles.
- Gel early. First gel at ~30 minutes, then steady intervals. Don’t wait for the wall.
- Drink small sips. Little-and-often beats big gulps for most stomachs.
- Smile for photos. It relaxes your shoulders and reminds you to enjoy it.
Race-morning mini-checklist
- Breakfast you’ve rehearsed (finish eating ~2–3 hours pre-start).
- Apply anti-chafe; bandage or tape any known hot-spots.
- Clip bib, pack gels, fill bottles, bathroom stop, then kit up.
- Plan how you’ll find your supporters after the finish (phone meeting point).
